Hi, Community!
Have a question for general discussion.
In ObjectScript we have cls for classes and mac code, which both compile into int code.
Is there any reason when you use mac instead of cls for non-persistent classes?
For me the benefits for cls are:
1. Inheritance and other OOP features
2. Auto-documented code
For mac one visible benefit is easier call in terminal:
do method^Utils(p1,p2)
vs
do ##class(Package.Utils).method(p1,p2)
What is your choice and why?

Hi, Community!
Continuous Delivery is a software engineering approach in which teams produce software in short cycles, ensuring that the software can be reliably released at any time. It aims at building, testing, and releasing software faster and more frequently. The approach helps reduce the cost, time, and risk of delivering changes by allowing for more incremental updates to applications in production.
Join us at 07:00 UTC, April 24th for a webinar with a live demo "Git flows and Continuous Delivery" by @Eduard Lebedyuk
The language of the webinar is Russian.

Hi, DeepSee experts!
I need to call a listing programmatically other than the default.
I can do that with %LISTING keyword. E.g. in Samples:

But how can I call custom listings in MDX? E.g.
Hi, Community!
I’m sure you are using Developer Community analytics built with InterSystems Analytics technology DeepSee:
You can find DC analytics n InterSystems->Analytics menu.
DC Analytics shows interactive dashboards on key figures of DC entities: Posts, Comments, and Members.
Since the last week, this analytics project is available for everyone with source code and data on DC Github!
Hi, Community!
Please share your experience on code deployment on production site. Do you compile ObjectScript on Production? Is it OK?
Or you only compile on Test site and copy cache.dat to a Production?
Hi, Community!
I'm using Git with DeepSee and when I need to do a commit to the git repo I'm exporting ALL the pivots and dashboards from the namespace. But I can forget to do that) And it can take time for a large system.
What is the way to manage automatical export of DeepSee artefacts which we are editing in UI (Cubes, Pivots, Dashboards, Pivot Variables, Term lists, Shared Measures) into files every time when I push Save button?

This year we again introduced three annual badges on Global Masters Advocacy Hub to let you remember how much you contributed to Developer Community in 2017. Here they are:
Hi Community!
Coding guidelines discussion. Consider you have For with one command in the cycle. Here are the options:
One
For i=1:1:1000 set ^Test(i)=""Two
For i=1:1:1000 {
set ^Test(i)=""
}Same for the "If":
if a set b=aor
if a {
set b=a
}
Your choice? Or maybe even other options?

InterSystems Data Platforms and performance – VM Backups and Caché freeze/thaw scripts, by Murray Oldfield 1752
Hi, Community!
Someday you find yourself having a wonderful class package which can be helpful in several projects. So it is a library package.
How to make the classes available for different namespaces in Caché? There are two ways (at least two ways familiar to me):
1. Start the name of the package with %, like %FantasticLib.SuperClass. Wrong way.
If you do that the class would be placed in %SYS and would be available in other namespaces.
This is wrong because of the two reasons:
1. The class will be wiped out with the next Caché update (as all the %SYS Namespace).
2.

Hi, Community!
Consider you move data from one server to another or make a deployment with persistent data. What do you do with index globals?
Is it always better to rebuild them or there are some cases when it worth to take them too?
